I'm not familiar with Elixir or Debootstrap (I'm guessing web-oriented)? But, I've had great success with using WSL for C++ oriented projects, building with both g++ & clang. Only issue in that regard I've had is that the emulated syscalls cannot currently enumerate ethernet devices. The calls are implemented, but fail at runtime currently. I've not yet filed a bug report, because I don't know how it should perform.
